For factories, cold stores, farms and logistics hubs
A battery behind your meter, engineered from your own bills.
See your payback, return on investment and the money a battery generates over ten years, then get a plan an installer can quote.

30-second estimate
What would a battery earn for your site?
Rough indication only, before any bill is read. Your plan replaces it with a quarter-hour simulation.
The journey
Five steps, with AI doing the paperwork and engineers holding the gates.

Upload your bills
Twelve months of invoices or your quarter-hour curve. AI reads tariff, power terms and penalties.

Talk to the copilot
It asks only what the engine needs, at most three questions at a time.

Supplier-ready plan
Sizing, layout, container spec and prices from vetted vendors, ready for quotes.
Have ready: 12 months of bills (PDF or photo), your CUPS or supply number, a photo of the transformer plate and the space available outdoors.
Your final report
A decision your board can sign, not a brochure.
- Clear recommendation: install, install with conditions, or wait
- Return on investment and money generated after 10 years
- Payback with a cautious and an optimistic case
- Battery size, layout and connection option
- Buy, lease or energy-as-a-service comparison
- Permit checklist and supplier-ready specification
A 522 kWh / 250 kW battery pays for itself in about 4.8 years and leaves the site about €310,000 better off after 10 years, after paying for it.
Illustrative example, not a real client.
Built for energy-hungry sites
Manufacturing
Shift peaks, lower contracted power, protect lines from micro-outages.
Cold storage
Steady night loads and expensive peaks: ideal for time-of-use arbitrage.
Agri-food & farms
Store midday solar for irrigation, packing and evening processing.
Logistics hubs
Charge fleets without a new grid connection or excess-power penalties.
Where the money is
Contracted-power terms, excess-power penalties and price spreads between cheap and expensive hours. Best cases: 1.5–2 cycles a day and 150 kW+ of peak shaving.
Buy, lease or as a service
Compare paying upfront, an 8-year lease with no money down, or energy-as-a-service, all on the same numbers.
AC by default
Container batteries on your internal AC network: simplest to permit and to connect alongside existing solar.
Questions
Does it cost anything?
No. Exploring, simulating and the first plan are free and carry no commitment.
How accurate are the numbers?
Bills give a class B estimate; a quarter-hour curve gives class A. Every figure shows its class, with a cautious and an optimistic case.
Where do battery prices come from?
From the HELIOS vendor and price master (28 September 2026) covering 16 suppliers, CATL as primary. Written quotations replace estimates as they arrive.
Do I need a new grid permit?
Usually not: batteries on your internal AC network with anti-export control avoid a new connection. The plan tells you exactly which permits apply.
What if I already have solar?
Better. The battery stores surplus solar and the model counts it; AC coupling works alongside your existing inverters.
Who sees my data?
Only you and HELIOS engineers. Files stay in private storage and are never shared with suppliers without your approval.
Your bills stay in private storage. Estimates, not guarantees, until measured data and an engineer review confirm them.
